Viewing multiple monitors in a montage view is very simple in ZoneMinder.
Create new group
From the ZoneMinder home page click on on the furthest top left link (see
diagram). This will open up the interface to create or select camera groups.
Highlighted groups link
On the camera group page click the "New" button to open up a dialog for
creating new groups. If you already have a premade group simply select the
group, click apply and go on to the next subheading.
Select camera groups form
From this dialog box enter a meaningful group name and select monitor Id's
that you wish to be a part of this group. ( to select more than one monitor
hold down the shift key while clicking the monitor name )
Select camera group members
Once you have made the new camera group select it from the camera group
selection page and click "Apply".
Open Montage View
To view a live stream of the cameras currently in your view simply click the
montage link. It is located in the top right side of the zoneMinder home page.
